'Plvorso' HUB.

SPECIFICATION forming part of Letters Patent No. 712,293, dated October 28, 1902.

Application filed. December 3, 1901. Serial No. 84,501. (No model.)

To all whom it may concern.-

Beit known that I, JACOB H. GENTER, a citizen of the United States, and a resident of Albany, in the county of Albany and State of New York, have invented a new and Improved Pivoted Hub, of which the following is a full, clear, and exact description.

The invention relates to road-vehicles having a steering-gear for the front wheels.

The object of the invention is to provide a new and improved pivoted hub which is simple and durable in construction, arranged to reduce the friction of the working parts to a minimum, and more especially designed for the front or steering wheel of a road-vehicle, to permit convenient and quick turning of the Wheel in the desired direction for steering the vehicle properly, and facilitating adjusting of the various parts, producing proper lubrication and rendering the device entirely dustproof.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is a cross-section of the bearing for the hub. Fig.'3 is a sectional side elevation of a modified form of the improvement. Fig. 4 is a transverse section of a modiiied form of the improvement, and Figf isa sectional plan view of the roller-bearing for the modified form shown in Fig. 4.

The front axle A of the vehicle is provided near each outer end with a vertically-disposed pivot B, preferably screwed into'the axle A and secured therein by a set-'screw C to firmly hold the pivot in position. lower ends of the pivot B screw cones D, engaging balls D', mounted in a cup D2, fitted in a recess E', formed in the peripheral surface of a tubular bearing E, having an elongated opening E2 in its middle portion to accommodate the outer end of the axle A. Nuts B' screw on the extreme outer ends of the pivot B to securely hold the cones D in position, it being understood that the said cones On the upper and a ball-bearing on the exterior periphery of the hub-bearing for the' bearing E to turn on in a horizontal direction and that the pivot B extends centrally in the recesses E' containing the ball-bearing. On opposite sides of the re- Y cesses E of the bearing E are arranged cones F, engaging sets of balls F', mounted in cups F2, carried by the hub G of the vehicle-wheel, it being understood that the said cones F, sets of balls F', and cups F2 form ball-bearings interposed between the hub G and the bearing E. Y

By the arrangement described it will be seen that the hub G revolves on the bearing E, which in turn revolves on the pivot B, the vertical plane of rotation of the wheel eX- tending through the axis of the pivot B, so that when the bearing E is turned ythe said plane of rotation of the wheel is shifted to cause the vehicle to steer either to the right or left, according to the direction in which the bearing E is turned. Y The outer cone F is held in place by a nut H in the form of a cap screwing on the outer end of the bearing E, and the inner cone F is held in position by a nut H', screwingon the inner end of the said bearing E. A spherical covering-plate I fits over the nut H free from'contact with the same and is attached to the hub G, and a spherical ring I' ts over the inner end of the bearing E, the nut H', and the outer portion of the inner cup F2 and free from contact with the bearing E and nut H', as plainly shownin Fig. l, the said ring I' being secured to the inside of the hub G. A spherical ring l2 also fits upon the hub G at the middle portion thereof, the said covering I and rings I' and l2 givinga spherical appearance to the hub and at the same time preventing dust from passing to the working parts. Flexible dust-rings J are interposed between the pivot B and the bearing E to prevent dust from passing by way of the axle A to the inside of the pivoted hub. Similar dust-rings J' are interposed between the nut H and the adjacent cone F and between the nutv D, the sets ofballs D', and the cups D2 form ing E in the desired direction to cause the Wheel to travel straight forward or turn to either side, according to the position of the steering-gear.

As illustrated in Fig. 3, the axle A carries at each end a pivot B2, the nuts B3 of which form cups for balls D3, engaging cones D4, screwed or otherwise fastened in a bearing E2, under the control of the operator, by a bar K' of the steering device. Nuts D5 screw in the bearing E3 at the top and bottom thereof to hold the cones D4 in position. The bearing E3 is also provided at its ends with annular flanges E4, carrying cups F3 for sets of balls F4, engaged by cones F5, screwing in the ends of the hub G of the vehicle-wheel, the said cones F5 being secured in place by rings H2 and H3, screwing in the outer and inner ends of the hubs G. A dust-cap J2 is secured to the outer end of the inner annular flange E4 and to the ring H2, so as to close the inner ball-bearing to prevent dust from passing to the inside of the pivoted hub.

In order to properly lubricate this device, I provide a pipe L, extending through the hub G to the inside thereof, the outer end being normally closed by a suitable cap L'. The pipe L is provided with branch pipes L2 L3, of which the branch pipe L2 directs oil to the balls D3, cups B3, and cones D4, while the branch pipe L3 directs the lubricant to the balls F4 and their cones and cups.

I do not limit myself to the particular construction of ball-bearings shown and described, as the same may be varied, and rollerbearings, for instance, may be substituted, as shown in Figs. 4 and 5. In this case the axle A2 carries a sectional pivot B4, formed with bearing-surfaces B5 forcone-shaped rollers N, journaled in outer and inner rings N and N2, fitted in a bearing E5 at the top and bottom thereof. The conical rollers N are engaged by rings D6, screwed in the top and bottom of the bearing E5 and held therein by suitable caps D7, which also have central olfsets engaging the inner rings N2 of the rollerbearings. It is understood that by the arrangement described the bearing E5 can be readily turned on the sectional pivot B4 and the friction is reduced to a minimum by the roller-bearings N.

Having thus described. my invention, I claim as new and desire to secure by Letters Patentl. A pivoted hub, comprising a pivot carried by the axle, a bearing carried by the pivot and on which the hub is mounted to turn, and a casing attached to the hub and inclosing the parts, as set forth.
